Hello,

        does anybody know how (and if is it possible) to store
lists,trees,hashtables... using EJB and representing a tree, a list.. with
an EJB? For example, when I've tried to do it with this CMP Entity Bean, the
EJB server said me "I don't know how to map my_list to database" (I'm using
WebLogic 5.1):

        class MyEJBLinkedList implements EntityBean {
                public Integer PK_MyEJBLinkedList; // The Primary Key
                public java.util.LinkedList my_list; // This is a Serializable object!!

                // The functions here are not important, the are very simple.
        }


TIA
